Accupro ACC-BBL140400 Boring Bar Left Hand Solid Carbide

Product Description

The ACCUPRO ACC-BBL140400 is a left-hand cut solid carbide boring bar designed for precision internal boring operations on CNC lathes and manual turning centers. Built from submicron-grade carbide with a bright finish, this bar delivers consistent cutting performance in tight-tolerance bore work. The 3/16-inch shank diameter and 2-inch overall length make it well suited for small-diameter bore applications starting at 0.14 inches minimum bore diameter, with a maximum bore depth of 0.4 inches. Machinists and toolroom operators use this bar when high rigidity and dimensional accuracy are required in close-bore finishing passes.

This boring bar is intended for small-bore internal turning applications in production and toolroom environments. Its submicron carbide construction handles a range of workpiece materials where tool deflection and wear resistance are critical. The left-hand cutting direction suits specific lathe setups and back-boring configurations where a right-hand tool cannot be used. It ships individually and is appropriate for job shops, production turning cells, and precision machining operations requiring consistent results in small-diameter bores.

Key Features

• Submicron solid carbide construction for rigidity and wear resistance in precision boring
• Left-hand cutting direction for specialized lathe setups and back-boring applications
• 0.14-inch minimum bore diameter allows work in very small internal features
• 0.4-inch maximum bore depth suited to shallow to moderate internal passages
• Bright finish coating on the shank and body
• 3/16-inch shank diameter with 2-inch overall length for compact toolholder compatibility

Compatibility

Designed as an OEM-style replacement or direct-fit boring bar for toolholders accepting a 3/16-inch shank diameter in standard CNC and manual turning center setups.

Installation Notes

Installation is performed by qualified machinists following standard toolroom procedures. Secure the shank fully in the toolholder to the recommended clamping depth to minimize overhang and reduce deflection. Power down the machine and verify spindle stop before changing tooling. Follow the machine manufacturer guidelines for feed rate, speed, and coolant application when setting up carbide boring bars.
